Spied! 2015 Chevrolet Silverado 3500 HD – High Altitude Testing

2015 chevrolet silverado 3500 hd chevy towing

Lookie what we got here!  The Fast Lane Truck team was busy running the light duty edition of our signature Ike Gauntlet extreme towing test, when we spied several camouflaged heavy duty GM pickup doing some high altitude testing of their own.  These guys were difficult for us to catch, as they noticed our cameras.  However, we managed to snap this very clear photo of the 2015 Chevrolet Silverado 3500 HD prototype.  You can clearly see the grill in this image, and it looks a lot like the front of the light duty 2014 Silverado that was a part of our test.


The headlights on this 3500 HD Dually prototype look identical to those of the light duty, and the grill has the same design.  The HD test mule has a unique large opening in the lower bumper to feed more air to the turbo diesel intercooler and other radiators.  The heavy duty also shares the aerodynamic front lower valance with the 1500.   Will the final HD product look nearly identical to the light duty from the front?

This flat bed dually has peculiar cargo.  It carried a current Chevy 3500 HD dually on a large goose-neck trailer.  This is a healthy load, considering a fully outfitted dually can weigh close to 9,000 lbs and that they were running the same stretch of I-70 and climbing to over 11,000 feet of elevation.

Check out the TFLtruck signature Ike Gauntlet test of the Ram 3500 HD dually.   And stay tuned for the huge light duty Ike Gauntlet series coming up later next week.  (Pssst.  You already know that 2014 Chevy Silverado will be in it.  It will also have two other 1500 pickups that we will reveal soon.)
